Yes.  PHP tries to be smart and sometimes it shoots itself in the foot
in doing so.  And yes, PHP only has one type of array.  And unlike Perl,
PHP associative arrays preserve the order of entries in the array--a 
feature I took advantage of in PmWiki 0.4.

However, I'm not sure I want to try to explain to a naive administrator 
why "11.1" comes before "2.5", or why $array["1.2"]  is different
from $array[1.2].  This is especially since PHP will accept both 
without warning but produce different and difficult-to-describe/explain 
results depending on which is used.
